I can't seem to connect these two stories. Can you please help?
I have heard that you have to turn electron by 720 degrees in order to get the same spin state. Has this been seen experimentally? How ...

A wheel of radius $R$ spins about its center with a centripetal acceleration of $v^2/R$.
I get that the acceleration at all points on the rim of the wheel point towards the center of the wheel. But, ...

If we apply a force on a fixed body and if that body rotates, we calculate torque about that pivot point. But if that body is not fixed and then we apply force that provides translational motion and ...

This question keeps me busy for couple of weeks. To be clear,
If I put a fluid into a blender and start it, it will spin in one direction. This will create a small vortex.
What if I am able to spin ...

I have a very simple problem, that I cannot wrap my head around and is hurting my brain. I have a very simple example of the problem, please consider the the figure below:
In the first picture, you ...

For instance, consider a weight on one end of the ring. Assume that the ring has negligible mass compared to the weight. When the weight splits into two, moves around the ring and recombines at the ...

I am not good at picturing either $SO(3)$ or $\mathbb R \mathbb P^3$, the latter denoting the real projective space.
Can someone give me a rough physical understanding of the geometry and implication ...

Here's the question.......Two point masses $m$ and $2m$ are attached at each end of a light rod. The rod is pivoted at the center and is free to move in a vertical plane. Then find the angle $A$ when ...

Is it possible for a satellite undergoing the process to overshoot the required rotation rate for tidal locking? For example, if its rotation rate is being slowed, can it become slower than it needs ...

Is there a testable model which explains why rotation of an object in space and straight-line acceleration appear to be absolute while uniform translation is relative? I know of Mach's explanation, ...

First question on stackexchange. Hopefully somebody can help me out. I'm struggling to express the following eloquently.
I have a rotating syringe tipped with a needle. rotation speed w, with radius ...

We recently went over some rotational motion in my freshman physics class, I had a question for the professor on your frame of reference, and how that would effect the rotation of the object.
Say you ...

With today's ultracentrifuge technology, they can spin so fast that the sample can be subjected to accelerations of up to 2 millions Gs. That is equivalent to two solar masses. Has someone tried to ...

If you are in a 2-D space the motion of any rigrid body is composed of 2 different things, namely rotation and translation.
If you are in 3-D space the motion of any rigrid body is also composed of 2 ...

Can the angular momentum of anybody regardless of whether its symmetrical about the center of mass or not be found by finding the angular momentum about its center of mass and summing it up with the ...

When a particle attached to a string rotates around a cylinder of finite radius, a point on the curved surface of the cylinder to which the other end of the string is attached, the particle spirals ...

I was driving the other day and couldn't help but look at all the wind mills in the wind farms. I know I am not doing the math correctly, but I want to know what is "really" happening when a windmill ...

When someone walks to the directly centre of a merry-go-round the total kinetic energy of the merry-go-round and person system increases. (assuming the kinetic energy due to the person walking to the ...

First off, I'm not a physics person, just a lowly software engineer with below average math skills. What I've written is a simple animation of a spinning wheel using C++/GTK/Cairo. It allows the user ...

I've designed an electronic device that uses a 3-axis accelerometer to measure the acceleration of an automobile. I'm only interested in accelerations in the plane of the road surface, so I want to ...

Does General Relativity theory correctly explain the ellipsoidal shape of the earth?
It seems it does not because the Thirring expression¹ for the force of a spherical shell—of mass $M$, radius $R$, ...
